Battery setup suggestions??

I'm converting an old riding mower into an electric kart. I'm only looking to have the machine go somewhere between 5-10 mph tops. I'm not looking to use a controller on this project, I just want the motor on or off. The motor I'm using is 90v, 15a, 4800 rpm.
My question is, what is the ideal battery setup for this?
I was planning on using 1 large marine deep cycle battery. The kart would probably only be used for about 2 hours between charges. Would this be adequate, or would I need to double or triple these up? Any advice would be greatly appreciated.

If your motor is rated at 90c a 12v marine battery wont cut it. Also why would you make a riding mower into an electric kart, im sure the stock mower would be more powerful and more fun.

Thanks for the quick repsonse! The riding mower was sold for parts, it's body and frame is in great shape but has no engine.
I had that electric motor allready, and thought it would be fun to use it in this project.
Do you have any reccomendations for a battery configuration for doing something like this, or am I going about this the wrong way? Thanks!!

Well, I went with a 24 volt system, and it gets upto about 8mph and runs for 2 hours. I put a lawn/garden battery to run accesories.
